Bis([mu]-di­phenyl­phosphan­yl)bis­[(tri­methyl­phosphane)cobalt(I)](Co-Co)

R. Beck and H.-F. Klein

Abstract: The title compound, [Co2{P(C6H5)2}2(C3H9P)4], was obtained by the addition of di­phenyl­phosphane to a solution of Co(CH3)(C3H9P)4. The dinuclear complex mol­ecule exhibits inversion symmetry with the inversion centre located between the two CoI atoms. The short Co-Co distance of 2.3670 (8) Å lies within the range of metal-metal double bonds. As a result of inversion symmetry, the four-membered Co2P2 core is rigorously planar, and the two bridging P(C6H5)2-ligands and the terminal C3H9P ligands are arranged in a pseudo-tetra­hedral fashion about the CoI atom.
